Odonata Fauna in Different Types of Vegetation in Ozamiz City

Odonata species is a good environmental indicator. They are sensitive to changes in temperature and weather conditions. The distribution variability of various groups and species of Odonata depends on the habitat and vegetation types. This study aimed to determine the Odonata fauna in different types of vegetation in Ozamiz City. Field sampling was done in agro-forested, agricultural and mangrove areas from January to March 2014 with a total of 180 man-hours using sweep nets. Taxonomic keys and published photographs were used in the identification process. A total of 13 species identified in the area. Prodasineura integra is an endemic species while all others are Asian species. High-flying Odonata of Family Libellulidae was the dominant species in all vegetation types with Diplacodes trivialis as the highest in relative abundance (18.18%). Some families of Odonata confined only to cooler areas are more likely to appear at high temperature. The presence of stenotopic endemic species (Prodasineuraintegra) in the agro-forested vegetation of Site A indicates a good quality inhabiting area for the species. Dendrogram analysis revealed that Odonata species in agro-forested vegetation and agricultural vegetation are of closer similarities while mangrove vegetation is the least similar. Shannon- Weiner index also showed low diversity index in all vegetation sites. The presence of eurytopic species indicates that the sampling areas are relatively disturbed. Low species richness, diversity, and endemism in all types of vegetation indicate that the disturbed sampled areas could not provide the suitable habitat for Odonata. This study contains information on the quality of the different vegetation types in Ozamiz City for possible conservation effort.
